I just located the fuse in the power cable mount, and the fuse is ok. I tested continuity with a multimeter... it is ok. Any other hints!? I also searched for blown out caps... they look fine and dandy the lot of em. I merely opened the rear plastic cover... the center part. Its all good so far... any hints will be amazingly appreciated...I just located the fuse in the power cable mount, and the fuse is ok. I tested continuity with a multimeter... it is ok.

Following the post on Solution #1 I checked the boards again, and completely removed the screws on the input panel (where you plug all the cables on the back of the tv set) and inspected the back of the two boards in there. Nothing burnt, or outta the ordinary. Fuse as I said on comment1 is ok, and capacitors do not appear blown up on the power board (assuming the board on top is the power board...).Following the post on Solution #1 I checked the boards again, and completely removed the screws on the input panel (where you plug all the cables on the back of the tv set) and inspected the back of the two boards in there.

OK, now we need to take some voltage measurement, we need to look for 5vdc standby voltage, you MUST have this voltage before going any further. Look at the coonector for labelling such as 5vstby, 5vby. Can you also the number of the board itself, send me some pictures will be great, budmrtn@aol.com

What ever you do, you must plug the TV into GFCI outlet or isolation transformer before working on it, lethal voltage presents!OK, now we need to take some voltage measurement, we need to look for 5vdc standby voltage, you MUST have this voltage before going any further.

More than likely your t.v has bad capacitors that power up the light bulbs that light up the screen. I had the same problem with a similar Polaroid t.v. and replaced two bad capacitors and that solved the problem. Take the back off of the t.v. and look for capacitors that are bulged at the top. The capacitors have the model number on the side. I found replacement capacitors at www.digikey.com for a very low price. Here is a video that you can watch on how to replace the capacitors. https://www.youtube.com/watch?v=YCSNWi3UHf4

If it is only the screen going black but the TV remains on and you can hear audio, then there is a problem with the backlight. It could be due to bad capacitors or it could be a faulty inverter. It requires repair by a competent engineer.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.http://en.wikipedia.org/wiki/Capacitor_plaguePlease post back what you find.

Your inverter boards need to be tested and serviced, these are circuits designed to control the light behind the LCD glass panel. It could also be the power supply not feeding 24volts too the inverter circuits. In that case the power board would need servicing.

Take it back if its under warranty if not get it serviced at your local repair center..
